Do you use it for chain lube?

Do you like it?

Does it get tacky, or stay wet?

Will tackiness cause resistance?

LBS mechanic uses boeshield. Cleans the chain with Super Clean first, follows with denatured alcohol(mixes with water and evaporates it), the sprays the chain with boeshield and wipes up the excess. Any lube NOT on the chain pins is unnecessary, and will pick up grime.

I use T-9 on my chains. It's also good as a framesaver and corrosion protection for parts on my daily commuter.

Boeshield is the only thing we use in the shop for chain lube. Each pin gets doused, then a damp T-9 rag gets run over the chain to cover the side plates. If the bike will be used in a wet environment, we are done right there. If the bike will be used in a dry environment, we wipe the chain down lightly with a dry rag to minimize dust and dirt cling.

It's the best stuff we've ever used. Long chain life. Non-existent chain noise. Great on pivot points and shifters.

I use Boeshield T-9 every 100 miles usually, more if I'm caught in the rain or have been riding dusty trails. My routine is to clean the chain with a Park Chain Cleaner using a degreaser first. Then I run the chain once or twice through the Park using water and a few drops of dish detergent. I dry the chain with a clean rag and then use a heat gun while turning the pedals backwards to complete the drying. I apply a drop of Boeshield to each pivot point on the FD and RD and the cable rub points under the bottom bracket . I apply a drop to to each pin and then let it set a couple of hours or overnight. I run the chain through a dry rag and I'm good to go.

It has improved my chain life and shifting is solid and quiet. I like it.

I'm not one to comment on these chain lube threads, but I ran out of chain-L a few months ago and decided to try something different, just to see if there was anything I was missing out on. One of the lubes I tried was Boeshield and it is not even close to chain-L. If you have not tried chain-L, you really should. It last 3-4 times longer than Boeshield. I cannot recommend chain-L enough, I just reordered and received my new bottle yesterday.

I think the Boeshield is one of those products that was not designed for bikes to begin with. It was for aerospace applications and then found its way in the marine business because of its anti corrosive characteristics. We would have to go back to the scientists and engineers who were responsible for Boeing's Boeshield and ask them to re formulate it for bicycle chains.

In the meantime, some of us still use it. On Ceramic Derailleur Pulley the jockey wheel will show a build up using Boeshield if its over applied. With a more thinner lubricant, that jockey wheel will show less of it.

I wouldn't be surprised if some of these bike lube companies really outsource their engineering and science to bigger companies like LPS Labs. Take a look at this:

Choice in chain lubes is apparently a very personal thing. I've tried Chain-L myself and agree it lasts longer between applications. So does heavy weight hypoid gear oil. Problem is - I've seen no first hand evidence myself that a longer lasting chain lube extends the life of the drive train and a lot that indicates that a drive train that gets cleaned and lubed frequently does last longer. And I haven't figured out how to clean a chain thouroughly without scrapping the lube.

So I clean and lube every few hundred kilometers. Good chainrings and cassettes cost more than a chain and I want to minimize wear on all surfaces.

The problem I have with Boeshield is its two-step application. Put it on in the evening, and remember to wipe the chain off in the morning. If you forget to wipe it down, it'll grow an impressive, gritty, mess on the derailer jockey wheels.

I have a repair stand so that make sit easy not to forget - I leave the bike on the stand until morning with a roll of paper towels on the handlebars. It keeps me form just riding off without wiping.

Chain-L is better/quieter/longer lasting but the I switched to Boeshield bicycle lubricant since I started riding in a sandy environment. Wet lubricants attract sand like honey. I work in aviation so I chose Boeshield for its corrosion resistance. I don't engage in the chain cleaning shenanigan of many BF members. I just wipe the (10sp) chain down in between lubes and replace them at ~4k miles.
